Seaming garter stitch pieces together is very simple once you learn how and the seam is practically invisible.

All you need to do is follow the flow of the bumps on each garter stitch ridge. And using the mattress stitch once again you will create a nice invisible seam.

Have a look at this photo. See how each ridge has a top bump and a bottom bump? All you’re going to do is seam into a top bump on one piece and a bottom bump on the other piece. Actually it’s more a weaving technique than mattress stitch but it looks great when you’re done.

And it keeps it all even and creates an invisible seam.

First Choice For Seaming Garter Stitch

First, you’ll need to thread your yarn needle with the yarn end if it’s long enough to seam with. If not get a fresh piece and cut about 10 inches.

With your yarn needle and yarn you’re going to join both garter stitch pieces. Push the yarn needle through the last stitch on one of your finished pieces and then do the same on the other piece like the photo above.

On the left piece (left photo), I went in the bottom bump so push yarn needle right through the bottom bump like right photo.

Move over to the other piece and push yarn needle through top bump all the way through see left photo. Move over to other piece and push yarn needle through the bottom bump, right photo.

Keep working each side the same way, going into a bottom bump on the left and a top bump on right.

And here’s the magic moment After about an inch or so (left photo) gently but firmly pull the yarn to bring both pieces together (right photo). Play with it a bit so the stitches line up nicely.

Just keep seaming garter stitches all the way up to the top of your piece of fabric. Pull it all together like in the photo above.

Here’s how I bring it all together at the top.

On left photo I’m at the top and finished seaming. On the right photo I push yarn needle through the loop beside the loop the yarn is coming out of.

On left photo I created a loop with the yarn and then on right photo I pushed yarn needle through the loop to secure it.

Then just snug up the yarn a bit and it’s all ready to weave in.

And this is how it looks when you’re done. The left photo is the right side and the right photo is the wrong side. You can see the orange a bit but when you use the same yarn it won’t show.

You can adjust the stitches along the seam a bit so that they line up better.

This is the seaming method I use the most for seaming garter stitch. However there are some who believe that when you seam the edge stitches it makes a very flimsy edge. In all honesty? I’ve never had a problem.

My knitting never fell apart and it works well for me. But I also understand. So below is another way for seaming garter stitch if you are worried and you just want a firmer edge. And actually it’s only one small change that’s really simple too.

Seaming Garter Stitch By Moving One Stitch Over

If you want a firmer edge to your knitted seam you can try this seaming technique.

Join the two pieces as shown on left photo then push yarn needle through top bump left photo and pull yarn through like right photo

Here’s where it changes slightly. Move over to other piece left photo and skip first bump Push needle into next bump, the bottom bump left photo, all the way through right photo Keep working seam this way.

On one piece (left photo) push yarn needle through edge bump and on other piece skip one stitch and push yarn needle through next stitch. In left photo I go into top bump and the right photo I go into bottom bump.

Once again, after about an inch gently but firmly pull the yarn to bring pieces together and then continue.

And you’re all done. The left photo is the right side and the right photo is the wrong side. There’s a small seam because you didn’t work that one edge stitch but it’s OK. No one sees it and you have a firmer garter stitch seam.

Here’s a seaming garter stitch knitting video that shows you the same technique using the edge stitches just like the first set of photos I showed you at the beginning of this page. Have a look.
